87 n/a auto to 2.3T 5 speed

Will need downpipe from turbo. Save your fuel rail from the Mustang. The 86 is differant. Get the Map/Bap sensor from the turbo car. Some say same as yours some some say differant. I side on maybe differant so why not get it and install. Reuse motor mounts from the Mustang. Will need to convert to serpentine belt. The 86 is v-belt type. As far as clutch hook up. Don't know so leave this to someone else. I would save my Mustang intake. It has a intake air sensor. If you upgrade to 87-88 computer/ big vam etc later you will need that sensor to hook up.

87 turbocoupe is a higher hp turbo motor. Better computer,vam etc. Only bad thing is IHI turbo. Can't be boosted past 20psi near as I can remember. Only building heat then and is overspeeded. But face it most of us won't go that high unless major modification. Head porting, etc.
